Rgstephe Posted July 4, 2016 Share Posted July 4, 2016 Here is what I am facing. 2010 Transit Connect engine was turning over but not starting, after some checking of the fuses under the hood it would no longer crank over. So had it sent to the dealership and they reported that the Main junction box under the hood had corrosion/rust from water getting into the junction box. The dealer stated that the junction box/wire harness had to be replaced, part and labor over $3500.00 (no way I can pay that much) They did get it running so I could drive it home. I have went through the junction box and cleaned all the fuses and contacts, I do not notice any apparent shorts in the wires. When I mounted everything back I am back to square one, no cranking over. Any suggestions would be great. I would like to keep from replacing the wire harness if at all possible.

mrtn Posted July 5, 2016 Share Posted July 5, 2016 Any auto electrician would patch it up for your for a fraction of the price. It's a rather simple junction box and pretty damn water tight. Does it light up any codes? Quote Link to comment Share on other sites More sharing options...
Rgstephe Posted July 7, 2016 Author Share Posted July 7, 2016 No not lighting up any codes. I believe I have narrowed down the issue, and the van has come to life again. I replaced the Shift lever diode, and the fuel pump diode. Before replacing I cleaned the contacts to remove as much rust and corrosion as I possibly could. I put a bit of dielectirc grease on the diode blades. Also the PCM Relay was a bit loose, and some working on that got it seated properly. So far so good, hopefully it is holds up.
